What is meant by six diversity attributes?
NUREG/CR-6303, “Method for Performing Diversity and Defense-in-Depth Analyses of Reactor Protection Systems,” describes a method for analyzing digital safety systems to determine points of design for which credible common-mode failures are compensated for by diversity or defense in depth. Diversity is complementary to defense in depth and increases the likelihood that defenses at a particular level or depth will be actuated when needed.
